Taking to Instagram, Thando shared her childhood memories of Madikizela-Mandela.

"My granny lives in the same street as mama [Madikizela-Mandela], and I went to a crèche literally next door to mama's house. I remember peeking over to try spot her or tata [Nelson Mandela]," she said in her post.

Speaking of her interaction with the freedom fighter, Thando thanked Zoleka Mandela for sharing her grandmother with her.

"It's in the last few weeks that Zoleka Mandela allowed me to share her granny. It's a gift I will forever cherish...thank you for your heart, your grace and for sharing your granny with us," Thando wrote.
